Install DD-WRT BIG Firmware On The Netgear WNDR3700 V3 (N600)

Install DD-WRT BIG Firmware On The Netgear WNDR3700 V3 (N600)

Version 3 of the Netgear WNDR3700 Router, (A.K.A. N600 Wireless Dual Band Gigabit Router), uses the Broadcom BCM4716 chip.

While this device is not officially supported by DD-WRT, I was able to get it up and running just fine with an older BIG firmware.

As with any hardware hacking tutorial, you do this at your own risk! If you make a new shiny brick, it isn’t my fault. 

1. Login to the web-interface for your router from a device connected via ethernet.  Then download this Mini CHK Build, extract the .chk file and flash it to your router.

UPDATE – MARCH 2015 – There is an official build of the initial CHK file for the WNDR3700v3 that can be downloaded from HERE.

2. After reboot, do a 30/30/30 reset and log into the newly installed DD-WRT web-management interface. Now download the V24 Big Build, extract the bin file and flash it to your router.

UPDATE – MARCH 2015 – There is an official MEGA build for the WNDR3700v3 that can be downloaded from HERE. If you do not need all the features of the MEGA build, you can install the MINI version which is available HERE.

3. Another 30/30/30 reset and the device is up and running with DD-WRT Big firmware:

The beauty of the BIG firmware is the ability to do WiFi HotSpot configuration as well as other fun stuff like running the Transmission BitTorrent daemon and setting up a proper NAS with USB storage.

  1. do you still have that WNDR3700v3? it appears that there is no wireless with latest dd-wrt.v24-23919_NEWD-2_K2.6_mega-nv64k.bin image. should I downgrade to the one you used last year?
